SAMUEL LANDER, OF BROOKLYN, NEW YORK.

TOP-SETTING FOR JEWELRY.

Application filed May 22, 1915.

To all whom it may concern:

Be it known that T, SAMUEL LANDER, a citizen of the United States, and resident of the borough of Brooklyn, in the county of Kings and State of New York, have in vented certain new and useful Improvements in Top- Settings for Jewelry, of which the following is a specification.

This invention relates to top settings for jewelry which can be interchanged fromone article to another, and has for its object the obtaining of suitable means for fastening the top setting so that it cannot be readily removed.

The construction generally provided for attaching interchangeable top settings to rings or scarf pins, consists of a threaded shank attached to the top setting, which in turn is screwed into a threaded hole in the top of the ring or the head of the scarf pin. The top setting, however, occasionally unscrews and is often lost.

My invention provides means for locking the setting after it is screwed in place, and thereby making it practically impossible to unscrew itself.

Tn the accompanying drawing, which forms part of this specification, and wherein similar numerals refer to similar parts wherever they occur, Figure 1. is a side view of a ring embodying my invention, Fig. 2. is a side view of a ring with a portion of the top or head shown in section to bring out the details of the construction, Fig. 3. is a section on line 4l-it of Fig. 2. with the locking device open, Fig. 4. is a section on line 44 of Fig. 2. with the locking device closed, Fig. 5. is a modified form of locking device and Fig. 6. is a scarf pin provided with my locking device with the top setting omitted.

The top of the ring (1) is provided with a threaded hole (6) while at its side it is provided with a notch (13) separating the upper portion (12) from the lower portion (1). The two portions of the top of the ring are held together by means of the bridge (7). The semi-circular disk (8) is attached to the head of the ring by means of the pin (9) and is adapted to fit into the notch (18) so that when closed its outer circumference becomes flush with the outside surface of the head of the ring as shown in Figs. 1 and 4, while its inner circumference is adapted to overlap a portion of the hole The top setting (2) containing Specification of Letters Iatent.

the stone (3) is provided with a threaded shank (4t) havlng an annular groove (5). The threaded shank (4:) is adapted to be screwed into the hole (6) of the ring (1).

The annular groove is so located that it will be opposite the notch (13) in the headof the ring (1) when the top setting (2) 1s screwed into the head of the ring. When the disk (8) is moved to the position shown in Fig. 4, its inner circumference will envelop the shank (4-) at the groove (5) thus locking it in place. It is evident that with the disk in this position, it 1s lmpossible to unscrew the top setting. The disk (8) is held in place by friction. If it is desired to provide against the disk working loose, the projecting lug (10) 1s provided to engage with the recess (11) in the dlsk (8). This, however, is seldom requlred as the disk 8) is generally securely held in place by friction. To remove the top setting, a pin or any pointed objectis inserted into the small gap between the disk (8) and the bridge (7) and the disk (8) is pulled to the position shown in Fig. 3, thus permitting the unscrewing of the top setting (2).

In Fig. 6 is shown a scarf pin (14L) provided with a head containing a threaded hole (6) and a disk (8) for locking the top setting (2) in place. In the scarf pin the bridge (7) is at the bottom while the disk (8) is placed at the top, so that in the normal wearing position, the disk (8) will have a tendency to stay locked over the shank (4).

In Fig. 5. is shown another method of locking the top setting (2) in place. The ring (19) is provided with a top having a threaded hole (20) and a circular groove (16). The shank (17) attached to the top setting (2) is upset at its end and threaded to fit the hole (20). The spring (15) shaped as shown in Fig. 5. is fastened to the side of the shank (17 while its top portion fits into the groove (21) of the top setting (2). It will be evident that when the screw (18) is screwed into the threaded hole (20) until the bottom of the setting (2) bears against the top of the ring (19), the projecting portion (22) of the spring (15) will fit into the groove (16). The elasticity of the spring (15) will keep the projecting portion (22) inside of the groove (16). If it is desired to remove the top setting (2), the end of the spring (15) is pressed in until the projecting portion (22) is disengaged from the groove (16), thus permitting the unscrewing of the top setting.

It will be evident that modifications of the construction shown can be made, employing the same general principle, I therefore do not wish to limit myself to the exact construction shown but wish to include all devices, employing the same principle.

Having thus described my invention, I claim as new and wish to secure by Letters Patent.

1. In an article of jewelry, the combination with a sunoortin bod of a removable top setting having a projecting threaded portion and an annular groove approximately at the middle of the threaded portion and extending from the surface of the latter inwardly, the threaded portion being adapted to be screwed into the supporting body and cooperating means hingedly connected to the supporting body for engaging with the groove in the projecting portion.

2. In an article of'jewelry, the combinationwith a supporting body, of a removable top setting having a projecting outwardly threaded portion and an annular groove approximately at the middle of the threaded portion and extending from the surface of the latter inwardly, the threaded portion being adapted to be screwed into the supporting body and cooperating means co1n prising adisk hingedly connected to the supporting body for engaging with the groove in the projecting portion.

3. In an article of jewelry, the combination of a removable top setting having a projecting threaded portion and a groove approximately at the middle of the threaded portion and extending from the surface of the latter inwardly, a supporting body having a threaded hole at its top and a notch at the side of the hole, a disk hingedly connected to the supporting body adapted to fit inside of the notch and adapted to engage with the groove in the projecting portlon of the top setting.

Signed at Brooklyn borough, city of New York, in the county of Kings and State of New York, this 20th day of May, A. D. 1915.
